Description
–
Read DMA PCI-X split transaction timeout
expired.
Read DMA Local Memory Write Longer Than
DMA Length Error.
Read DMA PCI FIFO Overread Error (PCI read
longer than DMA length.)
Read DMA PCI FIFO Underrun Error.
Read DMA PCI FIFO Overrun Error.
Read DMA PCI Host Address Overflow Error. A
host address overflow occurs when a single DMA
read begins at an address below a multiple of
4 GB and ends at an address above the same
multiple of 4 GB (i.e., the host memory address
transitions from 0xXXXXXXXX_FFFFFFFF to
0xYYYYYYYY_00000000 in a single read). This
is a fatal error.
Read DMA PCI Parity Error.
Read DMA PCI Master Abort Error.
Read DMA PCI Target Abort Error.

Description
This bit enables programmable extension header
#1. If this bit is clear, then the value programmed
in bits [15:8] of this register will be ignored. If this
bit is set, then extension headers will be checked
for a type matching the value in bits [15:8].
This bit enables programmable extension header
#1. If this bit is clear, then the value programmed
in bits [7:0] of this register will be ignored. If this
bit is set, then extension headers will be checked
for a type matching the value in bits [7:0].
–
These bits contain the programmable extension
header value for programmable header #2.
